Reviews recent research, which has strengthened the understanding of the links between climate and tropical cyclones (TCs) on various timescales

States that geological records of past climates have shown century-long variations in TC numbers

States that while no significant trends have been identified in the Atlantic since the late 19th century, significant observed trends in TC numbers and intensities have occurred in this basin over the past few decades, and trends in other basins are increasingly being identified

States that climate models mostly continue to predict future decreases in global TC numbers, projected increases in the intensities of the strongest storms and increased rainfall rates
